Empowering Data-Driven Stroke Treatment

About the NeuroVascular Research Foundation

The NeuroVascular Research Foundation (NVRF), a 501 (c) (3) non-profit organization, was established in 2001 for the sole purpose of hosting on-line databases (registries) to acquire outcomes data and facilitate the exchange of scientific and educational information obtained from such research.  With the inception of the INterventional Stroke Therapy Outcomes Registry (INSTOR), the first endovascular stroke therapy registry in the world, NVRF set its sights on improving emergency stroke care by enabling participating institutions to obtain performance reports that could assist with process improvement.   INTRASTOR, (the INTRcranial Angioplasty and/or STenting Outcomes Registry) was also created and hosted by the foundation to evaluate intracranial angioplasty and/or stenting for the prevention of stroke, but is no longer active.

The Board of Directors for NVRF includes:


The INterventional Stroke Therapy Outcomes Registry (INSTOR) is designed from the ground up as a complete solution for process improvement and quality assurance for all aspects of emergency stroke treatment.  Now in its third iteration, INSTOR was originally created as a dose ranging and efficacy study of the intra-arterial use of alteplase vs. reteplase for treatment of stroke. Primary and Comprehensive Stroke Centers use INSTOR to track emergency processes of care and subsequent clinical outcomes for Intravenous [IV] tPA and/or Endovascular Treatment of stroke (EVT).  “The History of INSTOR,” published in 2013, provides a comprehensive overview of the registry’s evolution and importance to the current practice of stroke.  Please refer to the FAQ for further detail.
